METAL WHEEL.

SPECIFICATION forming part of Letters Patent No. 425,993, dated April 22, 1890.

Application filed January 21, 1890. Serial No. 337,654. (No model.)

To aZZ whom it may concern:

Be it known that I, MAGLOIR DE thus, a citizen of the Dominion of Canada, residing at Auburndale, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Metal \Vheels; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to metal wheels of that character used upon bicycles, tricycles, velocipedes, childrens carriages, &c., and has for its obj eet to simplify the construction, cheapen the product, and provide for the removal of a defective or fractured spoke and the insertion of a new one without injury to the Wheel.

'Iheinvention consists in the parts and combination of parts hereinafter described, and pointed out in the claims.

In the drawings, Figure l is a perspective View of a complete wheel. Fig. 2 is a longitudinal vertical section through the hub, the spindle being shown in full lines. Fig. 3 is a perspective view of the hub.

A designates the hub, comprising the spindle B and end sections 0, each section being formed of a single piece of metal which subserves the purposes of a sand-baud D, and a fastening for the inner ends of the spokes E, the outer ends of the spokes being secured in the rim or tire F in any preferred manner.

In the ordinary use of wheels of the character described they are subjected to great strain, which results in frequent breakage, especially of the spokes; hence it is of importance to provide means by which a broken spoke may be removed and a new one substituted.

Another object necessary to be attained in the manufacture of wheels for the purpose described is to provide for the use of a minimum amount of the tin solution in tinning the wheel, thereby materially lessening the expense.

I attain the objects first by using a single spoke formed with. a rectangular hook Gat the extreme end, which engages with an ann ular projection II formed integral with the hub-section, and passing the spokes through perforations I formed in the sections, and then bending the spokes at right angles, as at J, and securing the free end to the rim, preferably by the usual mode of riveting, whereby proper tension is given to the spokes.

In order to avoid openings or recesses into which the tin solution may run to waste, as is the ease with that character of hub in which the sections are formed of more than one piece, or with hubs formed of sections comprising but one piece in which inclosed openings or recesses exist capable of holding a quantity of the tin solution, the sections are channeled out radially from the perforations I, each channel J being adapted to receive a portion of the spoke and be closed thereby to allow the tin solution to spread thinly and evenly thereon, a further object being to present a finished appearance to the outer sides of the hub-sections when the spokes are in place.

Upon the inner sides of the hub-sections the annulus II is recessed coincidently with each perforation I to allow the hook G to seat therein, thereby presenting a finished appearance and requiring a minimum amount of the tin solution in tinning the wheel. 7

In assembling the parts the free ends of. the spokes are passed through the perforations I until the hooks G are seated in place, when the free ends of the spokes are bent at right angles and secured to the rim, after which the wheel is tinned in the usual manner.

Should one or more of the spokes become broken, in order to remove the same it is only necessary to bend the spoke in horizontal alignment with the perforations through which it is passed and pulling it through the same, when another spoke may be substituted in the manner heretofore described.

hat I claim is 1. 111 a metal wheel, hub sections each formed with an integral sand-band upon the outer side, an annulus upon the inner side, and perforations transversely through the sections, in combination with spokes formed with hooked ends to embrace the annulus, and bent at right angles to pass through the perforations, as and for the purpose set forth.

2. In a metal wheel, a hub comprising a IO tions and resting Within the grooves and recesses and having ends formed to embrace an annulus, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I hereby affix my signature in presence of two Witnesses.

MAGLOIR DE MARS.
